I'm looking to upgrade my GPU from a 2060 Super to a Zotac Solid OC White Edition 5080. I currently have a Corsair RM750e power supply. Here's my setup: my CPU is a Ryzen 7 7800X3D on an ASRock Steel Legend X670E motherboard with Trident Z6 Neo RGB D5 6400 RAM, a Samsung 990 Pro SSD, and a Lian Li GA II LCD 360mm AIO cooler with three 120mm fans, plus seven Lian Li Uni Fan SL-Infinity 120mm case fans. Do I need a stronger PSU to support the 5080?

Nvidia suggests a minimum of 850W for the 5080. Since your CPU is less power-hungry, you might manage with the 750W, but it's not guaranteed. By the way, are you running your RAM at EXPO speeds? Also, check your Uncore frequency in CPU-Z.
I'd definitely recommend getting at least an 850W, even if yours might work.
